Tory leadership contender Jeremy Hunt has refused to guarantee that the UK will leave the EU before Christmas, but said he “expects” it to happen by then.
He would not say when Brexit would take place if he became PM, telling the BBC: “I’m being honest with people”.
Rival Boris Johnson said the UK would leave by 31 October “come what may”.
He also said his remarks on the UK ambassador in Washington, who quit this week over leaked criticisms of Donald Trump, had been “misrepresented”.
Mr Johnson added he did not accept that his failure to support Sir Kim Darroch during a debate on ITV earlier this week had prompted him to resign.
